EXTENSION ADJUSTABLE HANDLE.

Application filed January 6, 1921. Serial No. 435,558,

T 0 all whom it may 00mm.-

Be it known that I, GOTTLIEB L. E. KLING- BEIL, a citizen of the UnitedStates of America, residing at Omaha, in the county of Douglas and Stateof Nebraska, have invented certain new and useful Improvements inExtension Adjustable Handles, of which the following is a specification.

This invention relates to extension adjustable handles and it has forits object to provide a handle consisting of two parts adapted to bethrown to varying angles with relation to each other and locked inadjusted position to thereafter constitute a rigid member by whichmotion may be imparted to some other part. A handle of this type is ofvery general application. There are many places where it is desirabletoactuate a part by hand but where the space within which one is able towork is so limited that a long handle cannot be given the necessarymovement. A handle of the type comprising the subject matter of thepresent invention is useful in connection with automobile jacks,automobile spring spreading devices such as is shown in my copendingapplication serial number 435,559 filed on the 6 day of January, 1921,upon ratchet drills, upon wrenches and in many other places.

In the accompanying drawing:

Figure 1 is a side elevation of an extension handle constructed inaccordance with the invention; and

Fig. 2 is a plan view thereof.

Like numerals designate corresponding parts in both of the figures ofthe drawing.

Referring to the drawing.5 designates a shaft to be turned, said shafthaving an angular end 6 thereon, which receives a crank handle 7constituting one of the elements of the extension handle. While I haveillustrated the part 7 as being provided with an angular opening 8 toengage the angular end 6 of the shaft 5, it is manifest that thisangular opening might just as readily engage a nut, the head of a studor any other object to which a turning movement is to be imparted.

Given ample space within which to swing the element 7, it is manifestthat the simplest way of accomplishing the desired object would be tomake the element itself of sufficient length to get the necessaryleverage. However it is frequently the case that the room within whichthe element 7 may swing is so limited that this element must neces-Specification of Letters Patent.

sarily be made quite short. therefore provide the extension handle 9which has a yoke 10 pivoted thereto at '11. This yoke is adapted toembrace the handle 7 and to receive a wedge 12 which has teeth 13 thatare adapted. to engage with arcuate teeth 14 formed upon the handle 9.By a downward thrust upon the handle 9 the wedge may be forced frombetween the handle 7 and the handle '9. By then adjusting the handle 9toapproximately the desired angle with respect to the handle 7 and bythen forcing the wedge 12 into place and giving the handle 9 a slightupward pull, the wedge will be bound between the handles 9 and 7, andmovement may then be imparted to the liamle 7 by pulling upwardly uponthe han- This arrangement provides means whereby the handles 9 and 7 maybe adjusted at varying angles with respect to each other. Thus thehandle 9 may be adjusted to the position where it will most effectivelyclear obstructions. I prefer to attach the wedge 12 to the handle 9 bymeans of a cord or other flexible device indicated at 15 which serves toprevent loss of the wedge and holds the wedge always in assembledrelation with respect to the handle 9.

It is to be understood that the invention is not limited to the preciseconstruction set forth but that it includes within its purview whateverchanges fairly come Within either 7 the terms or the spirit of theaDDended claims.

Having described claim is: V

1. A device of the character described comprising a two part handle oneof which constitutes an operating extension of the other, means to whichone of said parts'is pivoted and which embraces the other of said partsand a wedge adapted to engage between said parts.

2. A device of the character described comprising a two part handleoneof which constitutes an operating extension of the other, a yoke towhich one of said parts is pivoted and embraces the other of said parts,a wedge adapted to fit between said parts and interengaging teethbetween said wedgeand the end of one of said parts.

3. A device of the character described comprising a two part handle oneof which constitutes an operating extension of the my invention, what Iother, a yoke adapted to embrace one ofsaid parts, means for pivotingsaid yoke to the other of said parts, said last named part having atoothed end of arcuate formation and a wedge adapted to fit between said5 parts and to lie within said yoke, said wedge having teeth along oneof its sides adapted to engage the aforesaid arcuate teeth.

4. A structure. as recited .in claim 3 in combination with means forholding said wedge in assembled relation with respect to 10 one ofsaidparts. I 1

In testimony whereof I afiix my signature .in the presence of twowitnesses.
